Harvey vs Kinetico — your questions

What people ask when choosing between the two.

Which is better, Harvey or Kinetico?

Both are excellent non-electric twin-tank systems. Kinetico is generally more expensive but offers a longer warranty (10 years vs typically 5) and a slightly longer expected lifespan. Harvey is more compact, often cheaper, and uses block salt which is widely available in supermarkets. The best choice depends on your budget, install space, and how long you plan to stay in the property.

Are Harvey and Kinetico both non-electric?

Yes. Both brands use the kinetic energy of water flow to power their valve mechanisms. Neither needs a power socket, neither has timers to set, and neither adds to your electricity bill. This is a key advantage they share over electric timer-based brands like Monarch.

Which brand is cheaper to run?

Running costs are very similar. Both use block salt (around £60–£120 per year) and both regenerate on demand rather than on a fixed schedule. The main cost difference is the upfront purchase price and the length of warranty cover.

Can I get quotes for both brands through your service?

Our installer network includes dealers for Harvey, Kinetico, Monarch, Tapworks, and Culligan. The number of quotes and brands available to you depends on installer coverage in your postcode area — in some areas you may receive one quote rather than several.
